Exclamation Can you put a TOGA bottom for a skyview

Got a question as I install my panal upgrade to the Dynon HDX system.
Does it provide a pin for a toga button?

Any other great ideas for the Dynon upgrade please chime in.

If you want to get technical, and who doesn't, there is no TOGA function for the Skyview. There is a GO AROUND function that can be wired to an external button. This would activate the Go Around function, same as pressing the NOSE UP button on the display or the external A/P panel.

It is important to understand what the GO AROUND function does and does not do. It only works when the autopilot is active in VNAV mode (GS or other vertical guidance mode).

When Go Around mode is triggered it will
- Cancel VNAV mode and set into either VS mode at the default climb vertical speed target or IAS move based on the current indicated airspeed. You chose the behavior in setup.
- Lateral autopilot mode changes to TRK mode using the current track
- Aural annunciation "GO AROUND"
- Visual annunciation "ADD POWER"

Go Around mode will not
- do anything unless you are using the autopilot in VNAV mode
- change anything other than what was listed above
- follow a published missed approach procedure. If your IFR navigator provides one, you must reengage NAV mode to use it. Skyview has no vertical guidance available for missed approach procedures.

With all this in mind, it is still a useful function. If you do install a Go Around button, give careful consideration to its location. It will not be very useful if it is away from your normal hand position when you would be initiating a go around. I have mine immediately above my throttle knob and you'll find that most people have done a variation of the same.

Thatís a great detailed explanation. Thank you.
Is this out of the 27 pin from the primary screen only correct?

You can connect it to multiple displays (pin 27). You'll find everything you need in the SkyView System Installation Guide, available from the Dynon web site. Get the Pilot Guide and the AutoPilot Tuning Guide as well. They contain everything you need to know - those along with my own experiences is where my answer came from.

I used my Go Around button a couple of hours ago. It is really quite useful for IFR missed approaches.

I just did the screen harnesses today and I did 27 to the primary screen only. Should a single switch to both?

The dynon recommendation is to one screen for simplicity (not redundancy). You can wire it to both but a diode needs to be added to the wiring. The instructions are in the installation guide. The only downside to wiring to one screen is that if that screen is down for some reason, the go around button will not work.

I just wired to one screen, that switch is not critical to go thru the process of adding diodes etc. simpler is better.

Question Skyview Go-Around Button
